In this study, graphene oxide material was synthesized on the basis of modified Hummer's method and rGO was synthesized by green chemical reduction method, using extract from Celastrus hindsu benth leaves. The characteristics of structure, morphology, chemical composition and properties were determined by the measurements including XRD, FT-IR, Raman scattering, EDX, SEM, TEM, TGA/DTA. The results showedthat the graphite oxidation process had caused the appearance of many oxygen-containing functional groups, resulting in the surface morphology to become revealing a crumpled and rippled structure; the diffraction peak (002) at 26,5oshifted to 10,1oand the integer ratio atoms of C/O decreased. During the GO reduction, the polyphenol compounds in the extract reacted, leading to a reduction in the number of Ocontaining functional groups on the surface of the material, the diffraction peak (002) shifted to about 25o. However, the intensity of the diffraction peak was weak and the reduction was not complete. Finally, the thermal stability of rGO materials was better than GO, which was consistent with their structural characteristics.
